A condensate collector for easy gas-liquid-solid separation

Abstract

The invention discloses a condensate collector which is convenient for gas-liquid-solid separation, and belongs to the technical field of gas, condensate and impurity separation during pipeline pigging operations. The condensate collector has a U-shaped symmetrical structure, and specifically includes a first loading pipeline connecting pipe, a second loading pipeline connecting pipe, a liquid collecting steel pipe, a first connecting steel pipe, a purge pipeline connecting pipe, a second connecting steel pipe, and an inlet pipe. Gas port connection, gas outlet connection, third connection steel pipe, pipe cap, liquid sump connection and reducing joint. The condensate collector for gas-liquid-solid separation provided by the invention is easy to install, can improve the gas purification rate of the entire pipeline, reduce transportation difficulty, reduce operating costs and transportation costs, and can ensure stable gas supply and safety of equipment in the station.

Description

technical field [0001] The invention relates to the technical field of gas, condensate and impurity separation during pipeline pigging on-line and off-line, in particular to a condensate collector for easy gas-liquid-solid separation. Background technique [0002] The second phase of the Kazakhstan-China natural gas pipeline project starts from Beineu in Mangistau and terminates in Shymkent via Bazoi. It belongs to the second stage of the Central Asia natural gas pipeline. There is a big difference in technical indicators between Central Asia and my country's "Long-distance Natural Gas Pipeline Temperament Requirements" (Q / SY30). stricter. [0003] Condensate is produced during pigging operations and as natural gas travels along pipelines. Condensate and impurities will reduce the calorific value and transportation capacity of natural gas, which will not only increase the flow pressure drop and cause slug flow, but also accelerate the corrosion of pipelines and equipment by ...
